  • Patent number: 4460851
    Abstract: In a cathode ray tube (CRT) display system utilizing a semiconductor switch in the output stage of the fast scan axis, a resonant circuit is coupled to the flyback circuit for production of a dynamic focus voltage. The capacitance required for the flyback circuit is derived from the equivalent capacitance of the dynamic focus resonant circuit, thereby eliminating the need for a separate flyback capacitor.
